Issue:

computing king / knight / sliding piece masks may be expensive
it can be pre-computed and stored in an array, improving the overall draw-gen performance

Suggested Solution:

run pre-computation when loading the module, caching common move masks in arrays
for king / knight moves: replace the computation by a simple lookup
for sliding piece moves: combine a lookup with some bit hacks like hyperbola quintessence to determine blocking pieces
